Abstract (en)

[origin: EP0691754A2] A receiver and a method for controlling a receiver, the receiver being implemented on the RAKE principle and comprising a number of correlators (30a-30d) which are able to synchronize with a received signal. To effectively utilize the correlators of the receiver, the operation mode of the correlators in the receiver is changed dynamically in the method of the invention between the received signal tracking and acquisition modes according to the need. <MATH>
